Which of the following best defines a portfolio assessment?

A portfolio assessment is best defined as a systematic collection of materials selected to demonstrate a person's level of knowledge, skill, or ability in a particular area. This definition emphasizes that a portfolio is not just a random assortment of work but a curated selection that showcases the individual’s learning journey, competencies, and reflections. Portfolios allow educators to see a comprehensive view of a student’s growth over time, including various types of work such as projects, written assignments, and reflections that all contribute to assessing the learner's overall capabilities. By compiling these materials thoughtfully, students can present evidence of their learning process, critical thinking, creativity, and development in specific skills, making it a powerful tool for both assessment and instructional planning. This holistic approach contrasts with other assessment strategies that may focus on isolated performances or standardized tests.
